Under the feudal civilization system of the Great Zhou, data collection is actually not an easy task.

There is no Internet here, there is no direct search engine search, even libraries are rare, and knowledge is still a very valuable asset, which is not easy to obtain.

Yan'er can get this information in one night, which certainly has the influence of the power of the Song Mansion, and it also shows that her own ability is actually quite good, otherwise she would not be able to achieve such efficiency.

According to the data, there was no large-scale popularization of printing technology in this era, whether it was martial arts cheats or Confucian classics, most of them were transcribed manually, which of course would lead to a large number of errors or omissions or sentences.

At the same time, in the materials collected by Yan'er, in recent decades, there have actually been attempts to make stone or copper plates to engrave and print books, but in the end they have all failed, or have been sealed, and the technology has not developed.

"The technology is not mature enough, the cost of the formwork produced is very high, and there is a high damage rate, the private economy of Dazhou is not developed enough, few people are willing to make such an attempt, the last one is actually a ...... academy"

Song Yan couldn't help but shake his head slightly, after reading the information, he knew that there was still a lack of conditions for the natural development of printing in this era, and the root cause was cost.

There are only two sources of power for the development of all technologies, one is politics and the other is economic.

The causes of the former may be varied, leaving aside for the time being, the latter is of course just to make money, and technology that does not make money will never be developed until the day when the times make it profitable.

If the cost of printing is too high, it is better to find someone to copy it by hand, and the book market is not really opened, then of course no one will invest in research.

"Now the book market of the Great Zhou is monopolized by the major academies, literary miscellaneous periodicals are published by the academies, and the sage classics simply require students to copy by hand to deepen their memory, as for the martial arts classics, ......"

Song Yan couldn't help but shake his head again, Shenwutang didn't have the idea of spreading martial arts classics at all, the martial arts atmosphere of the Great Zhou Dynasty was self-cherishing, and even the apprentices were often dictated, who was willing to take out the martial arts classics and sell them?

"Sure enough, there is no soil for printing to survive at all, it seems that the Great Wednesday invention in a thousand years should have the name of someone in my Song!" Song Yan suddenly slapped the table.

Heaven does not give birth to me Song Hongwen, the printing house is like a long night!

Yan'er was awakened by him slapping the table, looked up at Song Yan blankly, and then fell down again.

Song Yan didn't care about her, finished reading the information in his hand, then put it aside casually, and began to carefully observe the little girl lying in front of him, a wisp of true qi poked out from his hand, gradually touched Yan'er's side, and began to swim in her body.

Yan'er didn't seem to be aware of this, and she didn't mean to resist at all, as if she was really asleep.

But there was still nothing abnormal in the result, Yan'er was no different from a normal person all over her body, and she couldn't see any traces of practicing any exercises.

The current Song Yan can be said to have seen all the exercises of Dao Buddhism and Demon Martial Arts, and he really can't see anything special, so he has to give up.

It didn't take long for a greeting to come from the rear, but it was the Jinggen monk, who was looking at Yan'er curiously: "Senior brother, why didn't you see you all night, and you deceived a little girl?"

The pure root monk is coming back from morning class. He didn't get up late, after all, he was a serious monk of Daguang Temple, he got up early in the morning to do morning classes, and his martial arts practice didn't fall at all, unlike Song Yan, a lazy man.

Yan'er was awakened by the sound again, and looked up at Monk Jinggen, who suddenly exclaimed, "Hey, what a handsome girl...... Amitabha, the poor monk is firm in his pure heart, don't mistake me!"

"What a heart to Qingqing, senior brother touches the heavens and the earth, and the junior brother admires!" Song Yan clenched his fists, and then waved his hand at Yan'er and said, "Okay, you go back to sleep first, you don't need to come over today, and you will come back tomorrow when you are full." ”

Yan'er was moved to tears, and after thanking Song Yan, she rushed back to sleep.

Song Yan didn't care about her, turned to Monk Jinggen and said, "Senior brother, I'm going to go out later, do you want to come along?" Or are you going to go to Liumen for a stroll?"

"Huh, what am I doing with Six Doors......

"Aren't you going to chase your Qingqing girl?" Song Yan patted him on the back and said, "You won't wait for the girl to come out to ask you out, right?"

Monk Jinggen shook his head and said, "I asked her about these before, and Qingqing didn't like them. ”

"And what does she like?"

She said she likes to investigate cases. ”

"Dead face, workaholic...... Why don't you, senior brother, go and investigate the case for her?"

“？”

......

In the end, the two brothers parted ways, and the Jinggen monk went to the six gates. In the end, he felt that his junior brother was right, no matter what, it was good to be close to Miss Qingqing.

And Song Yan went to Fangxing Academy in the south of Beijing, which is a medium-sized academy with a good reputation and teaching level, although it is not the top, but it is also a very powerful academy.

What's more, among the materials that Yan'er brought over, it was this academy that took the lead in developing the prototype of printing and tried to produce it, but it was finally shelved because of the cost.

But there is no doubt that Fangxing Academy has a relatively complete production process, which can undoubtedly save Song Yan a lot of time.

Printing technology must be developed, not to mention the Shenhai Realm Mental Method, Song Yan still has a large demand for the Yijin Sutra at the moment, and whether there will be new changes in the Yijin Sutra after the 100th level, this is also worth looking forward to.

Nancheng is not far from Song's house, Song Yan simply walked over, the winter in Beijing is not too cold, when Song Yan rushed to Fangxing Academy, he could still see many students coming in and out.

Song Yan found a few guards at the door, and said: "Student Song Yan, come to visit Mr. Fan Zhixian Fan today, and I will be tired and tired." ”

Because he knew that he was going to come to the academy, Song Yan specially put on a scholar's costume, and his predecessor was also a scholar, and he had a scholarly atmosphere, so it was perfect to visit the academy.

In fact, the academy often encountered scholars visiting the door, and several guards politely invited Song Yan into the courtyard, and then arranged for one person to pass on Fan Zhixian.

It didn't take long for Song Yan to see the target of this trip, Fan Zhixian who appeared in Yan'er's information.

Fan Zhixian, whose name is Jingyang, is forty-four years old, one of the actual administrators of Fangxing Academy, and is also the commander of the Great Zhou Taixue Superintendent, which is commonly known as the person who is in charge of the seal.

If all the draft documents are to be issued in the name of the superintendent, they must go through the hands of Fan Zhixian, the eight-rank Jingguan who is upright, and has the qi of merit to protect himself.

The official quality of the Great Zhou is very heavy, but it is not like the modern era of Song Yan's previous life, where a dozen first- and second-grade officials were dragged out and beheaded at every turn, and the prime ministers of the Great Zhou were usually only three or four grades, and the second-grade and above were all accumulated by many worships.

However, Fan Zhixian didn't have much to offer, walked into the guest hall quickly, and said to Song Yan with a smile: "Who is my Dao, it turns out that Hongwen is here! Hongwen hasn't seen him for a few months, could it be that he is immersed in hard study, and now he is finally willing to go out of the mountain?"
